Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates, generally, to the field of handheld apparatus to assist with igniting fires external to the apparatus.

BACKGROUND OF THE INVENTION

Initiation and control of fire is one of the oldest technologies known to humans and is arguably one of the most important technologies, in that nearly all modern machines owe either their existence or their operation in one way or another to humans' ability to control fire. Many devices for the initiation of a fire are known. These range from rubbing objects together to generate heat through friction, to the combination of chemicals to create a flame, to the use of electricity to generate heat or sparks.
A challenge facing some fire starting technology is the ephemeral nature of the physical entity created by the fire starting apparatus in the face of the resistance of certain target materials to flame. For example, starting a fire with a flint or with electrical sparks is difficult because the sparks created may cool before the material onto which the spark is directed ignites. Likewise, starting a fire by heating a material is difficult if sufficient temperature is not able to be maintained until the material ignites. Even devices that emit a flame, such a flame thrower or cigarette lighter, are only effective if the flame can be maintained in contact with the target material long enough for the material to ignite. Most often, the fire starting device continues to consume energy, whether in the firm of kinetic energy, chemical fuel, or electrical energy, throughout the time that the effort to ignite the target material is maintained. This, generally, also requires the user to continue to exert effort while waiting for the target material to ignite.
One approach that has been used in an attempt to address this issue is to combine the target material with accelerants or other target materials that ignite more easily. For example, materials that the user desires to burn may be covered in gasoline or mixed with more flammable materials, such as dried leaves. This approach makes starting a fire easier by decreasing the time and energy necessary for ignition. The ephemeral nature of the physical entity being used to create the fire remains an obstacle, if the entity is unable to be maintained long enough to cause ignition.
Another approach that has been used in an attempt to address the issues described above is to has been to arrange the target materials in a manner that protects a portion of the target area from the ambient conditions to slow the cooling or dispersal of the physical entity being used to create the fire.
The approaches described above are often cumbersome and do not lend themselves to easy operation, especially by a single user whose attention may be divided. Furthermore, the approaches described above are, generally, single-use approaches or are at least difficult to prepare for reuse.
There is, therefore, a need for a fire starting apparatus that dispenses material that has already been ignited and constructed in a manner designed to maintain the flame, especially a hand held apparatus capable of multiple use, single-handed operation, and easy reloading.

SUMMARY OF THE INVENTION

The present invention provides a hand held fire starting apparatus capable of being operated with one hand, dispensing a material that has already been ignited and that is constructed in a manner designed to maintain the flame until ignition of a target material, and having a fuel dispensing system that is both reusable and easily reloadable. The apparatus can include a triggering mechanism disposed on the outside of a housing and operably connected to an initiation device disposed within the housing. Depending upon the configuration of the housing, various safety mechanism may be in place to prevent accidental activation of either the triggering mechanism or the initiation device. Depending upon the configuration of the apparatus and the operating mode of both the triggering mechanism and the initiation device, the initiation device is configured to both ignite a flame in a fuel pellet and also to eject said fuel pellet from the apparatus. A plurality of said fuel pellets are present in the apparatus in a manner that stores them in a manner that operably isolates each fuel pellet from the remaining fuel pellets so that fire does not transfer from one fuel pellet to another, positions them for ignition and ejection, and automatically positions a new pellet after a pellet has been ejected from the apparatus. In one configuration of the apparatus, the new fuel pellet can be positioned manually, for example by rotating a cylinder, rather than being positioned automatically. Depending on the configuration of the apparatus, the fuel pellets may be present in a manner that is easily reloadable after fuel pellets are used and may be contained in a structure that is removable and replaceable with a structure that is loaded with new fuel pellets. Thus, the present invention creates a relatively durable flame expulsion from a hand held device that allows ignited flammable material to be relatively quickly ejected from the apparatus without the need for continued expenditure of energy and focus after the apparatus is triggered. The present invention further allows easy reloading of the apparatus to provide for repeat operation from a relatively compact device.
In one embodiment, present invention provides fuel pellets that contain a flammable material, such a paraffin, cotton, or wood particles, that have been coated in an accelerant or material with a low flash point lending itself to easy ignition, such as petroleum or alcohol. The best mode envisioned for such fuel pellets is a paraffin and petroleum combination, such as the Wetfire Tinder product produced by Ultimate Survival Technologies. One of ordinary skill in the art would understand that the material described herein are merely exemplary and that any combination of materials lending themselves to easy ignition and relative flame durability could be used as the base material or the coating. Said fuel pellets may be individually sealed such that the pellet is not directly exposed to the flame of a nearby ignited fuel pellet. In the preferred embodiment, the fuel pellets described herein are designed to be substantially entirely consumed by fire and do not have a substantial metal core that would remain after burning. Furthermore, in the preferred embodiment, the fuel pellets are designed to be ejected from the apparatus, rather than being contained with propellant in a metal container that remains after the ejection. One of ordinary skill in the art would recognize that at least these two characteristics distinguish the fuel pellets herein from tracer rounds for artillery. The foregoing notwithstanding, some metal may be present in the fuel pellets to assist in igniting or maintaining the flame.
In one embodiment, the present invention provides a system containing a plurality of fuel pellets in a rotatable cylinder containing a plurality of chambers, each of which contains at least one fuel pellet. Said cylinder is operably connected to the trigger mechanism and the initiation device in a manner that causes of the cylinder to rotation upon the ejection of one of the fuel pellets. Such configurations are well known in the art, with example being provided in U.S. Pat. No. 158,957 to Mason entitled Revolving Fire-Arms or U.S. Pat. No. 9430X to Colt entitled Improvement in Fire-Arms. In another configuration of the apparatus, the new fuel pellet can be positioned manually, for example by rotating a cylinder, rather than being positioned automatically. Said chambers may be modified by adding structures to either end a chamber to prevent the fuel pellets from inadvertently leaving the chamber when the apparatus is not in operation. As used herein, such structures may be referred to as retention structures. Such chambers may also be modified by adding structures to either end of a chamber to prevent flame from the ignition of one fuel pellet igniting other fuel pellets. As used herein, such structures may be referred to an isolation structure. In some embodiments, a single structure may serve as both a retention structure and an isolation structure. For example, a film placed over both ends of a chamber would act both as a retention structure in that it would tend to keep the fuel pellet in the chamber and also as an isolation structure in that it would tend to contain a flame in a single chamber after ignition so that it does not transfer to fuel pellets in other chambers. Alternatively, a plurality of fuel pellets may be contained in a magazine structure such as that described in U.S. Pat. No. 3,087,270 to Stoner entitled Ammunition Magazine with a Spring Coil. Said magazine structure could be modified by providing retention structures, isolation structures, and/or a separation structure designed to physically separate the fuel pellets. One of ordinary skill in the art would understand that the chambers, magazine structures, retention structures, isolation structures, and separation structures described herein are merely exemplary and that any structures tending to maintain the fuel pellets in position for use and also preventing the transfer of a flame from one fuel pellet to another may be used. The best mode envisioned includes a rotatable cylinder containing six chambers each containing one fuel pellet and have films covering both ends of the chamber. One of ordinary skill in the art would also recognize that the chamber could be modified to facilitate ignition and burning of the fuel pellet. For example, in one embodiment, the chamber may have structures inside the chamber that are rubbed on by the passing rod from the initiating device to created additional friction against said rod and create more sparks. One of ordinary skill in the art will understand that this is only one example of such chamber modifications, and that the chamber can be modified in any way that might help to facilitate ignition of the fuel pellet.
In one embodiment, the present invention also provides a trigger mechanism disposed on the outside of the apparatus housing. Said trigger mechanism may be mechanical, electrical, biometric, or any other type of device that allows the users to activate the apparatus. For example, a mechanical trigger mechanism may be slideable, depressable, liftable, or rotatable. An electrical trigger mechanism may include any type of electrical switch or connection or transceiver. A biometric trigger mechanism may include a finger or palm printer reader or facial recognition. Trigger mechanisms of many kinds are well known in the art. Once of ordinary skill in the art would understand that the trigger mechanisms described above are merely exemplary and that any structure that allows the user to active that apparatus may be used as the trigger mechanism. The best mode envisions for the trigger mechanism is a slideable mechanical trigger that can be slid to toward the back end the housing with a single finger, preferably a thumb. The best mode further envisions safeguards on the trigger mechanism, such as an indirect or obstructed slide path, to help prevent inadvertent activation of the apparatus.
In one embodiment, the present invention also provides an initiation device operably connected to the trigger mechanism. Such connection may be through mechanical linkages, electronic wiring, electromagnetic signal transmission, or any other method of causing the initiation device to activate upon activation of the trigger mechanism. The initiation device is configured such that, upon activation, it ignites a fuel pellet and also ejects the fuel pellet from the apparatus. The best mode envisioned for the initiation device is a ferrocerium rod, such as that used in the BlastMatch product sold by Ultimate Survival Technologies, inside of the apparatus housing and connected to a spring such that upon activation the rod if propelled into the cylinder holding fuel pellets such that a pellet is ignited and pushed out the front of the apparatus housing. One of ordinary skill in the art would understand that the initiation device described herein is merely exemplary and that any device that would cause the fuel pellet both to ignite and to be ejected from the apparatus may be used as the initiation device.
In one embodiment, the present invention provides a port for the fuel pellet the exit the apparatus. In the best mode envisioned for such port, the port is a passive opening the opening of the apparatus housing. Said port may also contain a small tube leading to the outer edge of the fuel cell chamber, to help direct the ejected fuel cell. Said port may also be covered to help protect the apparatus from the entry of foreign material and to help prevent blockage of the port. One of ordinary skill in the art would understand that the description for the port provided herein is merely exemplary and that any structure that would allow a fuel pellet to exit the apparatus may be used.
Other features and advantages of the present invention will be apparent to those of ordinary skill in the art upon reference to the following detailed description taken in conjunction with the accompanying drawings.
